Value-packed features make these meters a must for everyones Tool Kit . Common Features: DC Voltage to 1000V AC Voltage to 750V DC Current to 10A Continuity test Diode test Drop resistant case Magnetic hanging strap Magnetic Hanging Strap Single-handed operation The ergonomic design allows both left and right handed users to rotate the knob while holding the meter in one hand. While one hand keeps the probe on the circuit, the other hand changes the meters function. This speeds up troubleshooting because you dont have to locate the probe point in the circuit again. This convenient feature allows you to hang your DMM on any magnetic metallic surface freeing up your hands for troubleshooting.
